在正常情况下，炼油厂石化厂产生的可燃气体，进入气柜储存，然后经压缩机进行抽取加压，火炬气脱硫后送到工厂燃料气平衡系统。在这种情况下，火炬系统是关闭的。炼油厂泄放的可燃气体全部回收利用，通过火炬气脱硫进入全厂燃料气平衡部分。全厂燃料气平衡通过汽化器、球罐保证燃料器压力平衡，使全厂用气装置正常运行。
一旦遇到意外情况或者发生事故状态，生产装置紧急停车会泄放大量的可燃气体，这些气体大大超过正常回收量，气体回收部分是无法进行全部回收的，一旦大量气体进入回收系统，会对气柜造成危险，以往的做法是关闭气体回收部分，并且马上点燃火炬，把进入气柜的可燃气体切换到火炬头进行燃烧排放，然而这种做法也是十分浪费资源的。
所以采用我们的火炬一体化 FCS 系统可以在紧急排放的时候，经过我们的优化软件平台处理后，保证气柜上升速度在安全状态下同时也可以进行火炬气回收，从而可以更好的节省能源，避免浪费。\
ystem can be connected to both conventional I/0 and various field bus devices such as Profibus, FF, CAN, and Modbus. system tool

can. The process control stage realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control.
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as I/0 or field instruments) adopts the international standard field controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world.
Line international standard, divided into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
